Webinar: GraphQL Federation and Knowledge Graphs

An online webinar to understand GraphQL federation and its ability to scale RDF based Knowledge Graph projects. Discussion included: -What is GraphQL -Bridging GraphQL and RDF -Bounded context architectures and improving team velocity -GraphQL federation Lab exercises and demos will include: 1) Building an Apollo GraphQL Service for Web Annotation JSON-LD stored in MongoDB 2) Modelling Star Wars RDF and automatically exposing GraphQL queries and mutations 3) Building a GraphQL Service to discover the semantic similarity between Star Wars characters (using vector spaces) 4) Building a single data graph across the three services. To provide a unified GraphQL interface for retrieving Star Wars character annotations, in context within a Knowledge Graph and using semantic similarity to discovering similar characters. Source code will be provided in Github. Some experience with RDF, JavaScript, Node is desirable.
